      @xinzo Looking into the FOG programming code. I see here: https://github.com/FOGProject/fogproject/blob/171d63724131c396029992730660497d48410842/packages/web/lib/reg-task/registration.class.php#L328

      OK lets hack our way into a possible solution. Again the caveat here is I have not tried this so I have no clue if it works.

      But at this location: https://github.com/FOGProject/fogproject/blob/171d63724131c396029992730660497d48410842/packages/web/lib/reg-task/registration.class.php#L328 Line #328 there is this section of code.

                  $autoRegSysName = trim($autoRegSysName);
                  if (strtoupper($autoRegSysName) == 'MAC') {
                      $hostname = $this->macsimple;
                  } else {
                      $hostname = $autoRegSysName;
                  }
                  $hostname = trim($hostname);
                  if (!self::getClass('Host')->isHostnameSafe($hostname)) {
      

      I wonder if we can tweak it to look like this

                  $autoRegSysName = trim($autoRegSysName);
                  if (strtoupper($autoRegSysName) == 'MAC') {
                      $hostname = $this->macsimple;
                  } elseif (strtoupper($autoRegSysName) == 'SYSSERIAL') {
                      $hostname = base64_decode($_REQUEST['host']);
                  } else {
                      $hostname = $autoRegSysName;
                  }
                  $hostname = trim($hostname);
                  if (!self::getClass('Host')->isHostnameSafe($hostname)) {
      

      Inserting this code

                  } elseif (strtoupper($autoRegSysName) == 'SYSSERIAL') {
                      $hostname = base64_decode($_REQUEST['host']);
      

      The file can be found here.
      /var/www/html/fog/fog/lib/reg-task/registration.class.php

      So now if we turn on autoprop and set sys name to SYSSERIAL would it insert the hostname value we configured in the fog.auto.reg file?

      Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

        I have the MAC adress of the computer instead of the ‘PC-*’.
        The SYSSERIAL is defined somewhere in the php script ?

          @xinzo said in Use serial number as hostname in Fog:

          The SYSSERIAL is defined somewhere in the php script ?

          I made that variable up for the hack to the script.

          In this specific code section I look for the word SYSSERIAL

                      } elseif (strtoupper($autoRegSysName) == 'SYSSERIAL') {
                          $hostname = base64_decode($_REQUEST['host']);
          

          So if the autoRegSysName (the field where you have MAC now or PC*) equals SYSSERIAL then remember in the previous steps you added the value host to the curl call in fog.auto.reg?, It will take the value of host and assign it to the variable $hostname. Its a similar concept to the line above that looks for the word MAC and then assigns the mac address of the target computer to the $hostname variable. In the fog.auto.reg file you adjusted earlier the $host variable is created by the fog.customhost script, right. Its a bit of a complicated path but when all of the bits are in place it should give you the autonaming function as with the full registration process.

          Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

            Okay I understand.
            In my fog.auto.reg the curl is sending to this script :

            ${web}service/auto.register.php 2>/dev/null)
            Maybe there’s something to do with this file ?

              auto.register.php

              Yes that is the file you will edit on the FOG server itself. It should be in the path I provided previously. Now that I think about it I might want to change the auto prop value to CUSTOM instead of SYSSERIAL and then make a write up on this for those fog admins that want to create a custom auto name value. I always use the full registration on my campus so I never thought about the auto naming process. I think you are onto something that will be useful to other fog admins.

                I’ve done it !
                The “old” fog.auto.reg is :

                if [[ -f "/bin/fog.customhostname" ]]; then
                    . /bin/fog.customhostname
                fi
                
                if [[ -f /sys/firmware/acpi/tables/MSDM ]]; then
                    productKey=$(tail -c+57 /sys/firmware/acpi/tables/MSDM | base64)
                fi
                while [[ -z $res ]]; do
                    res=$(curl -Lks --data "host=${host_default_name}&sysserial=${sysserial}&sysuuid=${sysuuid}&mac=$mac&productKey=${productKey}" ${web}service/auto.register.php 2>/dev/null)
                

                Here is the trick :

                while [[ -z $res ]]; do
                        host=${host_default_name}
                        host=$(echo $host | base64)
                        res=$(curl -Lks --data "host=$host&sysserial=${sysserial}&sysuuid=${sysuuid}&mac=$mac&productKey=${productKey}" ${web}service/auto.register.php 2>/dev/null)
                

                We have to convert to base64 and then send to the script. It works like a charm.
                I suceeded when I inspected the fog.man.reg.fix Here is what helped me :

                while [[ $res != "#!ok" ]]; do
                    if [[ $host_default_name != "" ]]; then
                        read -p " * Enter hostname for this computer [$host_default_name]: " host
                    else
                        read -p " * Enter hostname for this computer: " host
                    fi
                    host=${host:-$host_default_name}
                    if [[ ${#host} -gt 15 ]]; then
                        host=${host:0:15}
                        echo " | Truncated to 15 characters: $host"
                        usleep 2000000
                    fi
                    host=$(echo $host | base64)
                    res=$(curl -Lks --data "host=$host" ${web}service/hostnameloop.php 2>/dev/null)
                    [[ $res != "#!ok" ]] && echo "$res"
                
                
                done
                

                Those line
                host=${host:-$host_default_name}
                host=$(echo $host | base64)
                res=$(curl -Lks --data "host=$host" ${web}service/hostnameloop.php 2>/dev/null)

                Thank you very much for your help 😁

                  @xinzo well done! Now just make sure you backup everything since you hacked the fog environment. That way when/if you upgrade you don’t lose your hacks. But really nice. I’m really more than willing to help someone help themselves success with FOG. This way you can get exactly what works for your situation.

                    Thanks 😁
                    For people who want to do this. Don’t forget to set the QUICKREG SYS NAME in the FOG SETTINGS to SYSSERIAL.
                    @george1421 Can I upload my file somewere for the people who want to implement the feature ?

                      @xinzo If you want to post them here, I’ll rewrite the instructions as a tutorial and then provide a link to this thread. You might need to change the extension of the files to .txt so they can be uploaded. I can see other wanting this feature too. I know I personally missed it since the FOG v0.30 days.

                        Here are my files, I’ve upload all the content of my postinitscripts folder:
                        fog.postinit.txt
                        fog.patch.customhostname.txt
                        fog.man.reg.fix.txt
                        fog.customhostname.txt
                        fog.auto.reg.txt

                        Without you, impossible to implement this feature. Thanks a lot
